Abstract Proximate composition and heavy metal accumulation
in the muscle of deep sea crustaceans viz.,
Acanthephyra armata, Heterocarpus gibbosus, Plesionika
spinipes and Puerulus sewelli were analyzed. Crustacean
samples were collected from Lat. 11.026o –
11.405oN; Long. 74.508o – 75.212oE and Lat. 17.103o
– 19.983oN; Long. 83.042o- 87.428oE at the depth of
200 – 1200 m off west coast and east coast of India.
Moisture content was higher in H. gibbosus
(81.84±0.11%) off west coast and P. spinipes
(81.05±0.36%) off east coast, highest protein content
(20.34±0.48%) was observed in P. sewelli from west
coast followed by H. gibbosus (17.42±1.10%) off east
coast. Fat content of the samples varied from 2.3-
3.8%; with the highest in A. armata collected from
west coast, whereas ash was higher in A. armata
(2.21±0.14%) off east coast. Analysis of heavy metal
content indicated higher levels of zinc in samples
off west coast while iron and cobalt content was
significantly higher in east coast samples. Lead was
below detectable level in the samples analysed and
cadmium was detected only in H. gibbosus off west
coast. The deep sea crustaceans analysed in the
present study contained significant quantity of
protein and hence can find market in the food
industry. Heavy metals analysed were within the
prescribed limit, indicating that the selected stations
of Indian EEZ are free of heavy metal pollution.
